Improved machine for disintegrating, dispersing



THOMAS CARR, OF BRISTOL, GREAT BRITAIN.

. IMPROVED MACHINE FOR DISINTEGRATING, DISPR SING, AND'MIXlNG FERTILIZERS ANDKQTHER` MATERIALS.

Specification forming part of Letters Patent No. 93,595, dated August 10, 1869 patentedA in England..

October 22, 1868. i Y

To all 'whom it mag/concern:

Beit known that jf, THoMAs CARR, of the city of Bristol,in the United Kingdom of Great Britain and Ireland, engineer, have invented new and useful Improvementsin Machinery for Disintegrating, Dispersing, or Mixing Various Substances and Articles of Manufacture; and I do hereby declarethe following to ybe a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters `of reference marked thereon.

My improvements are made upon that machinery for disintegrating 'artificial niauures and other substances, for which Letters Patent were granted to me for the United Kingdom of Great Britain and Ireland, known as Carr Disintegratorf andthe improvements to be hereinafter described are part of those for which Letters Patent have been granted to shaft, the two ends of which have bearings in l plumber-blocks, and the other set of cages is `mounted upon a hollow shaft which fits and rotates upon the solid shaft, and as the two shafts arerdriven atconsiderable. speed in op'-,v `posite directions, the friction upon the hollow Y shaft is double thatdue toits `own speed;

and besides this objection thebushes forming the bearing ofthe hollowshaftwear away rapidly, owing to the diflicultyof keeping the lubricating matter within. the shaft, 'and the result is excessive vibration inthe cage s,=be

sides other minor defects; and my invention relates to one of the methods'described in the specification of my aforesaid :British patent.

for obviating these ditculties. y

My invention consists in mounting eachof the two sets ofcages upon the end of a shaft,

`and inplacing these endsrofthe two shafts,

upon which the cages are secured, close together, or nearly so, and with the axes of the shafts in the same line, and each shaft in pedestals or plumber-blocks. v i

rlhe driving-pulleys maybe placed on the shafts between the two bearings, or upon the ends of the shaft ovcrhanging the outside bearing.

Figure 1 is a section of my improved machine, taken lengthwise of the shafts.

Only

. secure by Letters Patent, isy The mounting of veach of the two sets of two bars of each cage are shown. This figure also shows a cross-section ofthe bed or foundation. Fig. 2 is a plan view of the machine an the bed or foundation. y

The construction of the cages, the mode of feeding the machine, and the formation of the bed or foundation form no part of thepresent invention; but as the manner of constructing the cages of large machines, to be driven at great speed, of feeding the same, and of forming the bed or foundation is not .well known, I shall givesome information thereon in describing the drawings.

A is the shaft, upon thev end of which the large disk b is xed, which disk, for large machines, may be formedfby a cast-'iron center disk part, b', keyed to the shaft, having a Wrought-iron disk, b, riveted to the center part by,and to the wrought-iron disk rings b2 are applied to give increased strength where' n the holes are formed for the'bars which through both the disk 7) and rings b2.

c is the shaft for the inner disk, d, which is also formed by a cast-iron center disk, d', and

pass

a wrought-iron disk, d.

Thedisk and rings should be turned up true, and the cages balanced for high'speeds. The driving-pulleys b3 and d3 are placed upon the outside en dsof the shafts, which are driven in contrary directions. Y .f

masonry..

Thewmaterial 'Ito be operated upon maybe l fed by means of a hopper or spout, e, asy shown in Fig. 2. y l

What I claim as myinvention, and desire to cages upon the end .of a separate shaft, the two shafts .being placed end to end and in pedestals or plumber-blocks, substantially as hereinbefore described, and illustrated by the drawings.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
